Answer 1

Do something like this to check whether you app is in foreground or not by calling below method and depending on returning value true or false do your rest of work

public boolean checkApp(){
       ActivityManager am = (ActivityManager) this
                .getSystemService(ACTIVITY_SERVICE);

        // get the info from the currently running task
        List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);

        ComponentName componentInfo = taskInfo.get(0).topActivity;
        if (componentInfo.getPackageName().equalsIgnoreCase("YourPackage")) {
            return true;
        } else {
           return false;
        }
  }

Kotlin

 fun isAppRunning(context: Context, packageName: String): Boolean {
    val activityManager = context.getSystemService(Context.ACTIVITY_SERVICE) as ActivityManager
    val procInfos = activityManager.runningAppProcesses
    if (procInfos != null) {
        for (processInfo in procInfos) {
            if (processInfo.processName == packageName) {
                return true
            }
        }
    }
    return false
}
